In our analysis of the project, we observed that

1. 1 stubbing which stubbed getDatein SimpleSVNDirEntryHandlerTest.getEntry which is invoked inSimpleSVNDirEntryHandlerTest.addEntries but never executed by 3 tests: SimpleSVNDirEntryHandlerTest.testSortByName, SimpleSVNDirEntryHandlerTest.testReverseSortByName, SimpleSVNDirEntryHandlerTest.testFilter.

Unnecessary stubbings are stubbed method calls that were never realized during test execution. Mockito recommends to remove unnecessary stubbings (https://www.javadoc.io/doc/org.mockito/mockito-core/latest/org/mockito/exceptions/misusing/UnnecessaryStubbingException.html).

We propose below a solution to remove the unnecessary stubbings.
